The problem of two-dimensional area skeletonization that takes into account boundary features is considered. A modification of Zhang-Suen parallel thinning algorithm is proposed. The modification utilizes boundary tracking for boundary features detection. Skeletons that were obtained by means of the proposed method were found to be persistent to region rotation. The method was utilized for dactyl images skeletonization and processing.
Results of seismofacial researchs of carbonate and terrigenous sediments of South Near Board Part of the Dniper-Donets Depression are described (on the examples of Livensky Gas-Condencsate Deposit and Britaiska-North-Gercevanivska Field). Accumulative objects in the carbonate and terrigenous sediments have been described after the interpretation of received results.
